Rubber back liner for pump

Rubber back liner for pumps

Manufactured from 95% premium natural rubber renowned for its distinctive red color, Rubber back liners deliver exceptional performance in abrasive slurry applications. These critical wet-end components work with the pump casing to form the complete volute chamber, protecting the frame plate from wear while guiding slurry flow efficiently.

Introduction

Superior Material Properties

Rubber exhibits outstanding resilience, strength, and abrasion resistance in fine particle slurries. Available in material codes R55, R33, and R26, it withstands erosive forces through a unique liquid-phase vulcanization process that creates a highly elastic, self-healing surface. For corrosive environments, synthetic options like neoprene (S42) provide enhanced chemical resistance.

Key Performance Advantages

Extended Service Life: Superior wear resistance reduces replacement frequency by up to 40% compared to conventional rubber
Enhanced Efficiency: Maintains optimal pump performance by minimizing internal recirculation and preserving hydraulic clearances
Corrosion Protection: Resists degradation in low pH or chemically aggressive slurries
Easy Maintenance: Bolted (not glued) design enables quick replacement without disturbing piping or components
